ldpc-decoding SKILL.md skillA
ldpc-decoding from xi-zhao/openquantum is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add xi-zhao/openquantum/ldpc-decoding@git:20261012.5ce3b3ePins git:20261012.5ce3b3e in mdr.lock. Pin the fingerprint instead.

二元校验矩阵的 BP+LSD 解码，独立复核 syndrome 一致性。.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LSD 纠错解码
<!-- BEGIN NATIVE SDK ACCESS -->
## 原生 SDK 路径
本能力同时支持 **LDPC 的原生公开 API**。用户需要 自定义校验矩阵、错误模型、BP/OSD/LSD 译码器与批处理 时，由 Agent 在固定依赖环境中编写和运行任务代码，不限于下文便捷 Tool 的预设模型。
使用 `node scripts/sdk-access.mjs inspect ldpc-decoding` 定位环境，按[完整 SDK 工作流](../quantum-sdk-workbench/references/workflow.md)执行。模块导航：`ldpc`；导航不是 API 白名单。
下文关于模型、门集、输入与预算的限制描述便捷 Tool 的合同；原生 SDK 另受上游版本、可选依赖、宿主资源与用户授权约束。已禁用或被拒绝的动作不能借代码路径绕过。执行状态和科研验收分别报告。
<!-- END NATIVE SDK ACCESS -->
Agent 经 Harness 调用 ldpc_local 提供的 `decode_ldpc_syndromes`。本 Skill 负责选择和解释，不启动计算进程。
parityCheck 为 矩形二元矩阵，syndrome 数量由输入决定；每个 syndrome 长度等于校验数。假定独立同概率 bit flip。输出纠正向量、残余 syndrome 和是否满足校验；未给逻辑算符/真实错误，不能报告逻辑成功率或阈值。上游当前使用串行 LSD。
输入示例：
```json
{
"parityCheck": [
[
1,
1,
0
],
[
0,
1,
1
]
],
"syndromes": [
[
1,
0
],
[
1,
1
]
]
}
```
调用前确认用户问题落在上述范围内；参数含糊且会改变物理结果时先澄清。接口不接受代码、路径、凭据或真实硬件任务。
计算 worker 默认不设置时间或输出大小上限；部署可配置资源预算，取消会终止本次计算进程组。连接层超时与硬件环境配置见[资源配置](../../../docs/integrations/SCALABLE_BRIDGES.md)。
计算前显式准备固定依赖；运行仍可能写 SDK 缓存，因此保留 workspace-write。工具未注册或连接已禁用时，检查设置中心；不要用通用执行工具绕过禁用。

How to install
mdr add xi-zhao/openquantum/ldpc-decoding@sha256:3b7f0fbc2906bea3The line at the top of this page pins the label git:20261012.5ce3b3e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
